6\left(6x-8\right)+4\left(5x-4\right)-3\left(4x-2\right)=30
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3,4.
36x-48+4\left(5x-4\right)-3\left(4x-2\right)=30
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 6x-8.
36x-48+20x-16-3\left(4x-2\right)=30
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 5x-4.
56x-48-16-3\left(4x-2\right)=30
Pahekotia te 36x me 20x, ka 56x.
56x-64-3\left(4x-2\right)=30
Tangohia te 16 i te -48, ka -64.
56x-64-12x+6=30
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 4x-2.
44x-64+6=30
Pahekotia te 56x me -12x, ka 44x.
44x-58=30
Tāpirihia te -64 ki te 6, ka -58.
44x=30+58
Me tāpiri te 58 ki ngā taha e rua.
44x=88
Tāpirihia te 30 ki te 58, ka 88.
x=\frac{88}{44}
Whakawehea ngā taha e rua ki te 44.
x=2
Whakawehea te 88 ki te 44, kia riro ko 2.
